IMPIROVEMENT IN LIQUID-MEASURING SPIGOTS.

u Specification forming part of Letters Patent No. 149,186, dated March31, 187,4; 'application filed l February 4, 1874.

To all whom fit may concern:

Be it known that I, THOMAS NV. BLACKER- BY, of Stanford, inthe county ofLincoln and State of Kentucky, have invented certain Improvements inSpigots orDraft-Gocks, of which the following is a specification Theobject of my invention is to produce a registering-faucet, which shallpermit the escape of a certain determinate quantity of liquid wheneverthe faucet is used, and to provide, in connection therewith, aregistering apparatus, which shall record the number of times the faucethas been used, and so register the amount of liquid drawn therethrough.To this end, it consists in the combination hereinafter moreparticularly set forth and claimed, reference being had to theaccompanying drawings, forming part of the specification.

In the drawings, Figure l is a longitudinal section of spigot; Fig. 2,section on line a' .r of Fig. l; Fig. 3, section on line y y of Fig. l 5Fig. 4, section on line z z of Fig. l.

A is the outer shell of the spigot, which has screw-threads at B tosecure it firmly into the head or side of a cask or vessel in a iixedposition. C is an opening in said shell, which should be upward toreceive the liquor from D is the inner shell, which fits snugly withinthe outer, and is held to the outer with a nut on its small or innerend, v`which is clamped against the small end of outer shell to form aperfect loose joint between them. This inner conical shell is providedwith two or more openings or inlets, E, one of which, at each fractionalrevolution, comes opposite tothe opening C. It has also two openings, aa, opposite each other, and so situated, with reference to the two otheropenings E E that a line drawn directly through their centers wouldintersect .at right angles a line drawn through the centers of the iirstnamed. An opening, b, formed in the outer shell, has a pipe, F,extending from it,

which serves as a discharge to the liquor. G

is the space in the inner shell, intended to be sufficiently capaciousto contain a glass of liquor at a time,'any part of which may bedischarged when the opening a or a comes in line with opening b or tubeF. The spindle H, extending from the head of the inner shell,

4from the same the desired quantity.

has its end fashioned to t a key or -crank-le ver used to revolve theinner shell, and draw The pin d in the cylindrical groove e is 'situatedin such amanner with reference to the discharge-openings a a thatimmediately after the .iiow is cut off said pin, moving with the innershell, engages one ofthe teeth in the dia-l j", and records one drink.

The liquor may be allowed to run until the space G is exhausted beforeturning` for another supply; but, if only half, or any fraction of aglass, is called for, the moment after it is cut off the pin d engagesand moves the dial one unit space.

The dial f is xed on an arbor or post, about which it is allowed to movefreely. Arecorddial, xed above or at the side of the post, may be madeto move once at each entire revolution of the first to record thehundreds, or y any multiple of the spaces of the first dial. A smallhole is provided in the upper shell at K', which serves as a vent toassist the discharge of the cock.

To operate m'y device: The opening a bein g immediately opposite thedischarge-pipe F, one has to turn the key a quarter-revolution to theright, to bring the openings E E in line with opening O, to fill thespace Gr. Another quarter-turn brings the discharge-opening ce oppositeto, or in line with, discharge-pipe F. Another short movement, after therequired amount is drawn, brings the pin d in contact with the teeth inthe tirst dial, when one drink is recorded, whether it is small orlarge, and the proprietor credited with the fixed price for the same.

To prevent any back movement of the dial, a ratchet-wheel, l, is fixedabout the spindle H,

andis controlled`byapawl,h, which slips freely over the teeth when thekey is turned to the right, but which enga-ges them when any attempt ata back movement is made. A case, I, of suitable material, is provided tofit over the recording mechanism, to be fastened inside, by theangle-piece K, to the projecting metal at i. through which one may seethe dials as they record, but which can be touched only by the personholding the key to a lock which may be attached to the door of the caseas a It has a door with glass lights,

substitute for the temporary fastening shown in the drawing.

In describing my device Ihave dwelt particularly upon its applicabilityas a safeguard to proprietors dealingliquor by the small, While, with aslight modification, it may be madeuseful as a meter for liquidsgenerally, and applied Wherever they are drawn from vessels or pipes. Byattaching a pipe to the small end of the inner shell, and applying acock to same, with dial and other appliances, as shown and described, inthe larger end of a spigot, a complete measurer Will be obtained forgeneral use.

'What I claim as my invention, and desire to secure by Letters Patent,is-

l. A faucet, composed of the outer cylinder or shell A, and innercylinder or shell D, combined with the registering device, consisting ofthe lower toothed dial f and upper toothed dial f, in the manner and forthe purpose described.

2. Registering-dialsff, in combination With spindle H, provided withannular groove e and pin d, to actuate the registering device in themanner hereinbefore described and set forth.

3. In a measuring-faucet, as described, an

inner'cylinder, having the ratchet g and spindle H made upon the endthereof, and forming part thereof, substantially as described.
